Abstract
An electronic candle produces light using light emitting diodes (LEDs) or other electronic sources of light, rather than a flame, and is intended to operate the LEDs in a fashion that simulates a burning candle. The electronic candle includes a base and LEDs within a bulb and surrounded by a dome to provide a diffusing effect for light generated within the electronic candle. A memory accessible by a processor contains stored programming instructions causing the LEDs to illuminate under control of the processor, in accordance with particular modes of operation, varying from one mode to another after brief periods of time and in a random way. Each mode defines an apparent flame position having a radial position, angular position, and intensity of the simulated flame.
